Set in 2022, the film envisions an Earth plagued with problems
of overpopulation, global warming, exhausted food and fuel supplies,
and a corrupt government. Since most, or all, natural food sources are
"extinct" the only way people are managing to survive is by
eating a mysterious government endorsed substance called "Soylent."
But when a detective investigates the murder of Soylent Co. president,
the truths he finds, particularly that of the ingredients contained
in "Soylent Green" are more disturbing than Earth's current
turmoil.
